By means of first-principles calculations and crystal structure searching techniques, we predict that a different NaCaBi family crystallized into the ZrBeSi-type (i.e., P63/mmc) are strong topological insulators (STIs). Taking P63/mmc as an example, calculated band indicates there is inversion between two opposite-parity bands at Γ point. In contrast to well-known Bi2Se3 family, in has already ...

In the development of the multi-dimensional force sensor, dimension coupling is the ubiquitous factor restricting the improvement of the measurement accuracy. To effectively reduce the influence of dimension coupling on the parallel multi-dimensional force sensor, a novel parallel three-dimensional force sensor is proposed using a mechanical decoupling principle, and the influence of the fricti...

Couplings between protons, whether scalar or dipolar, provide a wealth of structural information. Unfortunately, the high number of H-H couplings gives rise to complex multiplets and severe overlap in crowded spectra, greatly complicating their measurement. Many different methods exist for disentangling couplings, but none approaches optimum resolution. Here, we present a general new 2D Jresolv...

This paper shows quantitative evaluation of coupling between a monopole antenna outside a shield case and a strip line inside that for a portable telephone. The amount of the coupling is calculated using FDTD method together width EMF method. This combination of methods can raise the calculation efficiency. Dependence of the coupling on the length of gaps, the height of the strip line and the l...

The purpose of this study is to determine the most stable fixation method for mandibular symphysis fractures by comparing the mechanical characteristics of models fixed at different positions with different numbers of plates. Fractures were generated in 3-dimensional finite element models, and were fixed with a single miniplate, parallel double miniplates, or perpendicular double miniplates. A ...

In this paper a four-pole elliptic function bandpass filter is designed with two ground slots. A research of microstrip bandpass filters (BPF) using defected ground structures (DGS) is presented. DGS technique allows designs of tight couplings without the necessity of using very narrow coupling gaps. The simulator Sonnet is used to design the resonator and to calculate the coupling coefficient ...

The 70.6 MHz llB NMR spectrum of (3)-1,2-B&H, consists of five doublets of relative intensities 2/3/2/1/l reading upfield. The proposed assignment of these doublet resonances is B (4, 7); B (6) and B (9, 12); B (5, 11); B (8) and B (10) respectively. The l ‘B NMR spectrum of [(3)-1,2-B&H, JZCocontains five doublets of relative intensities 1/1/4/2/l reading upheld The proposed assignment of thes...

In recent years, quasi-Newton schemes have proven to be a robust and efficient way for the coupling of partitioned multi-physics simulations in particular for fluid-structure interaction. The focus of this work is put on the coupling of partitioned fluid-structure interaction, where minimal interface requirements are assumed for the respective field solvers, thus treated as black box solvers. T...

A TeV-scale Higgs doublet with a small mixing to the standard model can have sizable Yukawa couplings several right-handed neutrinos and lepton doublets. This provides testable Dirac neutrino mass generation. We further consider seesaw mechanism involving $U(1)_{B-L}^{}$ gauge symmetry, which predicts existence of two stable fermionic dark matter, simultaneously explain between doublets generat...
